Forest River tail lights problem
Hello, Ken here. I am new to the forum. We just bought a 2005 Forest River TT to pull with a 1992 chevy 3/4 ton. The tail lights at the trailer do not work right. I checked the 7-way at the back of the truck with a volt meter and all work and are in the right positions. When I plug in to the trailer and turn on the running lights both tail light filaments on both sides shine dimly. Also, when I turn either the right or left turn signals on the turn signal filaments alternate right side, then left side, then right, and so on. It seems like I had this problem years ago and it was a ground issue. Any ideas would be helpful. I have not run down the trailer wiring yet. The wiring disappears under the holding tanks covers in the back so can't trace it exactly.
